Protective Action Mechanism of «EKOSTYM» Nanocomposite for Presowing Treatment of Seeds

Abstract: The state of the water in the KCl hydrated powder and KCl/AM1/H2O composite system in the air with the addition of hydrophobic organic compounds was studied by low temperature 1Н NMR spectroscopy. It was founded that presence of hydrophobic nanoparticles in composite system consisting of KCl hydrated salts powder and AM1-300 hydrophobic nanosilica (stimulating and protective nanocomposite system «Ekostym» analogue) significantly increases water binding to the surface. As a result water retention in the composite is significantly highher than in powder fertilizers. There is an additional increase in water inter facial binding when KCl/AM1/H2O composite system contacts with hydrophobic substance that mimics the hydrophobic surface areas of seeds. It is probably due to free energy gain in the result of splitting water clusters in nanoscale systems with hydrophobic and hydrophilic components.
Keywords: 1Н NMR spectroscopy, strongly- and weakly bound water, water clusters, composite system, mineral fertilizers, seeds.
